The MJO is building in Phase Space 6 with forecast to Phase 7 this week as it moves through the Western Pacific. The PNA is positive now and is expected to remain weakly positive for the foreseeable future with some strengthening possible at the end of the month.
This week will begin cold then warm to above normal by mid week as the off shore ridge builds over the state. The mean position of the eastern pacific ridge will remain west of Hawaii, so the west coast will still be subject to weather systems effecting it.
With AAM on the increase and MJO headed for Phase space 8, the likelihood of large storms such as the one we had last weekend is becoming less likely through the end of the month and into early April….
This next weekends storm will be a slow mover and will take to the end of the weekend to get here. Both EC and GFS do get it here through eventually. The EC is the slowest and is currently preferred by MammothWeather.com.
RE: Weekend system:
Please revisit last weeks discussion in regards to the upcoming weekend system
